Outdoor faucet or adapter for indoor sink for power washer

[briarpatch]

I like the mixer idea. I'll be doing something similar in my house, as the laundry room is adjacent to the garage, and easy to get the water supply out there. My focus is to create a place where I can wash cars indoors......having a 31x28 garage helps a little too

Thanks for all the replies, I guess exactly Y hose mixer is what I am looking for. Hope that works well enough.
Sorry @spazzz , but maybe I couldn't understand you if you are for or against those mixers.

Anyway I will make cold & hot spigots, even if I don't use the hot water spigot I don't lose anything, it's better to have it now that I am renovating rather than drilling afterwards. Anyway I think it will be really handy for the wash bucket when I want warm water instead of trying to fit that bucket under the sink.

Just I need to really find what would be the best way to mix those and if that Y hose mixer is good enough?

Maybe another valid question would be - do you rinse with warm water?
I will be using warm water for my two buckets, but when rinsing - I guess it doesn't hurt for the water to be a bit warmer? Especially when outside temperatures are close to 0 Celsius / 32F ?

Plus one for the Y hose mixer like Paul says. I run one in my shop!

I've read that it could cause issues with the hot water finding it's way up the cold line or vice versa. I'm not sure how true this claim it and haven't really experienced this issue first hand.

99% of the time I'm only on cold water but when you need the hot water to melt ice off a car it's a god send.

The Y mixer adapter is a great simple solution if there is no sink involved.
